//! Client connection and gRPC performance benchmarks
//!
//! This benchmark suite measures the performance of TLI client operations
//! including connection establishment, request/response cycles, and streaming.
//!
//! ============================================================================
//! TEMPORARILY DISABLED - Missing type definitions
//! ============================================================================
//!
//! This benchmark file references types that don't exist:
//! - `ServiceEndpoints` - not exported from tli crate
//! - `TliClient` - not exported from tli crate
//! - `Order`, `ListOrdersResponse`, `OrderUpdate` - missing proto definitions
//!
//! TODO: Fix by either:
//! 1. Adding missing exports to tli/src/lib.rs
//! 2. Rewriting benchmarks to use available types from tli::prelude
//! 3. Adding missing proto definitions
//!
//! See Wave 36 - Agent 10 for context
